While it's unknown what Cablevision and a Brooklyn energy company offered in their proposals submitted to meet yesterday's filing deadline, the Jets' offer is considerably bigger than their original $100 million proposal.

The new number would also trump what Cablevision and energy supplier TransGas had previously placed before the cash-strapped Metropolitan Transportation Authority.

MTA spokesman Tom Kelly said the agency, which rejected two other suitors yesterday who failed to include a $25,000 deposit, was not yet prepared to reveal details of the bids. The winner is expected to be announced March 31, although officials cautioned it might be later.

The Jets' new bid came as Cablevision bolstered its attack against the stadium, which it sees as a competitor to its flagship, Madison Square Garden.

At a noontime press conference, it offered the first glimpse of its plan with a development it called Hudson Gardens, a largely residential community with 5,800 new apartments and a 5-acre park.

Cablevision's plan also includes moderate-income housing, an elementary school, a library, a hotel, public toilets, theater equipment suppliers and a supermarket.

"The least interesting places in cities are those places where a huge chunk of land is devoted to one single use," said architect Alex Krieger.

A source close to Cablevision said the bid was not contingent on zoning changes, which would be needed to proceed. The stadium proposal has the support of city and state officials.

While impressive in its architectural renderings, the Cablevision plan was short on specifics. Officials would not say who would pay for some of the costly features.

They did project that the development would generate $100 million in state and city taxes by 2012 and fill 3,200 construction jobs over 12 years.

The Jets, who dispatched 11 former and current players to submit their proposal yesterday, want to build a 75,000-seat stadium on the site, allowing Gang Green to return to the city after more than 20 years of playing their home games in Giants Stadium in New Jersey. The stadium would also anchor the 2012 Summer Olympics, should the city be chosen.

The team has said the project would create 18,000 construction jobs and 6,900 permanent jobs, and the city estimates it could see $60 billion in new tax revenue the next 30 years.

"We need a team here in New York, and the Jets are going to build this stadium," said Joe Klecko, a defensive lineman for the team, who was one of the players to usher in boxes of documents on the stadium to the MTA's midtown headquarters.

Also in the bidding war is TransGas, which has offered the MTA $700 million in return for the promise of the agency's support of its plans to build a power plant in Williamsburg. It also wants the MTA to buy its power for 20 years.

Mayor Michael Bloomberg continued his public support of the stadium, which he has called key to the city's hopes of landing the 2012 Summer Games.

But he added that if the MTA gives the nod to Cablevision, the city would cooperate with their development.

In his first budget address to lawmakers, Democratic Gov. Tom Wolf laid out an ambitious $33.8 billion spending plan that raises taxes a combined 16 percent while slashing corporate and property taxes, restores cuts to education and wipes out the state's deficit.
